3Com NBX 3107 Cordless Phone - 3C10407A "no service"

[bolannos]

Hi community!!!

I use a 3COM phone system with many 3103 and one 3107 device. The 3107 handset can't connect to it's base and I don't know why. Ethernet cable is OK, power in base is OK, base is ON with red light. I cannot find an advanced guide that can show me the way to pair both, handset and base... Is there any keys combination or something else I can do for linking these devices and fortunately use my expensive IP phone???

Regards... Pedro.
